Patent JP-H08327397-A (JP)
Title: Encoder with function for compensating a/d converter offset
Inventor: TANIGUCHI MITSUYUKI
IPC: G01D5/245
Filed: 1995-05-31
Abstract: PURPOSE: To compensate an angle error due to offset by providing an operation means for obtaining the difference of A/D converter output for an input signal and a signal for compensating offset. CONSTITUTION: When SW2 of a signal switching means 2 is off and SW1 is on, a sinusoidal wave (s+h) is inputted to an A/D converter 4 and is converted into a digital signal (S+H+A) to be outputted. On the other hand, when the SW1 is off and SW2 is on, a reference voltage (h) is converted into a digital signal (H+A) by the A/D converter 4. Then, a difference signal S between both output signals is obtained by the operation of an operation means 3. A signal C is obtained as in a sinusoidal wave (s) also for a cosine signal (c). An X, Y-θconversion means 6 inputs the digital signals S and C from the operation means 3 as X and Y signals to obtain an angle signal. With the digital signals S and C, the amount of offset which the A/D converter has, is compensated so that the error due to the offset of the obtained angle signal is eliminated.

Title: Air cooled-type fuel cell
Inventor: FURUKAWA SANEHIRO
IPC: H01M8/04
Filed: 1985-07-15
Abstract: PURPOSE:To improve safety, by putting hydrogen occlusion alloy on the passage of air circulated/supplied in a cell stack. CONSTITUTION:Manifolds 2 and 2' for air and manifolds 3 and 3' for hydrogen gas are mounted on respective facing surfaces in a cell stack 1, with the hydrogen gas supplied into the stack 1 through an open passage and on the other hand, with the air supplied through a circulation passage containing a blower 4 and damper 5. In this case, while regulation of the damper 5' allows one part of exhaust gas to be exhausted outside through an exhaust valve 6, the other remaining part enters a circulation branch 7 and mixed with the fresh air introduced in conformity with the exhausted-air amount, and then returned to the stack 1. Introduction of the fresh air enables partial-pressure drop of oxygen in the air to be compensated and besides the stack to be cooled. In this method that the air serves as both reaction and cooling, hydrogen occlusion alloy 10 is put inside the enlarged-diameter part 9 of the circulation branch 7. The hydrogen occlusion alloy 10, minutely pulverized, is envelopped by a wire gauze made of nickel, stainless steel, or the like, and fixed on the inner wall of the enlarged-diameter part 9. Hence, the safety for the fuel cell can be improved without hydrogen gas accumulated inside the passage.

Title: Semiconductor photodetector
Inventor: YAMANAKA MORIHIDE
IPC: H01L31/10
Filed: 1987-06-23
Abstract: PURPOSE: To realize suppression of inflow of minority carrier to the adjacent photosensitive element part of the dead band without increase of junction capacitance by diffusing a metal element which shortens the diffusion length of minority carrier into a semiconductor substrate.  
     CONSTITUTION: A metal element which shortens diffusion length of minority carrier is diffused into a semiconductor substrate 1. As a metal element, Au, for example, is used. Diffusion of metal element is carried out, for example, by thermal diffusion after a photodetector part 2 is provided to a semiconductor substrate 1 consisting of Si wafer. After the photodetector part is thus formed, a necessary electrode is formed, it is then cut into chips and a semiconductor photodetector part of one chip can be formed. In a semiconductor substrate 1, the region other than that providing the photodetector part 2 becomes the dead band. Thereby, the minority carrier which is generated by the light irradiation to dead band flows or the minority carrier generated at the other photodetector part and flowing through the dead band can be lessened by shortening the diffusion length of carrier.

Abstract: PROBLEM TO BE SOLVED: To reduce the recoiling being produced from a rigid metal bump by providing a plurality of physical and electrical connections between the I/O pads of an integrated circuit element and the I/O pads of a substrate such that each connection includes multiple conductive fine particles and one or two composite bumps. SOLUTION: An integrated circuit element 30 is bounded to a substrate 10 such that multiple conductive fine particles 22 of an anisotropic thin film are present between the composite bumps 41, 43 of integrated circuit element and the corresponding I/O pads 12 of substrate 10.

Title: Relative speed controller for rotary head type digital tape player
Inventor: YOKOYAMA YOSHIHIKO
IPC: G11B15/473
Filed: 1989-06-21
Abstract: PURPOSE:To eliminate a need of a relative speed detecting circuit to perform the control without hindrance regardless of unrecorded parts on a tape by giving a tape speed and a drum rotational speed so that the speed component in the direction of the recording track of the relative speed vector of a head is equal to that for standard reproducing. CONSTITUTION:Since the rotating mechanism of a drum 12 and the feeding mechanism of a tape 16 are different in the rise response speed, respective target speeds are stepwise raised to approximate the relative speed to a target value even at the time of rise. The target speed of one of the drum rotational speed and the tape feed speed is calculated and given in accordance with the detected value of the other for the purpose of approximating the relative speed to a prescribed value, thereby approximating the relative speed for rise to the target value. In this case, rotation of the drum is controlled based on the tape feed speed because the response speed of the drum 12 is higher than that of the tape 16. Thus, a relative speed detecting circuit is unnecessary and the control is possible even in unrecorded parts of the tape 16.

Title: Optical recording and reproducing device
Inventor: TATEZONO FUMIO
IPC: G11B7/00
Filed: 1989-06-20
Abstract: PURPOSE:To prevent the occurrence of defocusing on a tape surface and the directional deviation of laser light reflected from the tape by keeping the optical axis of irradiating laser light perpendicular to the tape surface and rotating an optical head centering around a shaft which is in a perpendicular direction to the tape surface. CONSTITUTION:The optical head 6 is rotated centering around the shaft 15 which is in the perpendicular direction to the surface of a tape 1, while keeping the optical axis of the irradiating laser light perpendicular to the surface of the tape 1. Therefore, a guide is not needed and it is possible to always hold the focusing spot of the irradiating laser light on the tape 1 without the applica tion of excess force on the tape in such a case that the tape is obliquely wound around a cylinder. Thus, the defocusing can be prevented and also the direc tional deviation of the reflected laser light can be prevented because the optical axis of the laser light irradiating on the tape 1 agrees with the optical axis of the laser light reflected from the tape 1.
